In an organic electroluminescence device in which one or more organic compound layer is interposed between a pair of electrodes constituted from an anode and a cathode, the organic compound layer comprises a hole transporting layer and/or a hole injecting layer, and polyarylamine having a specific structure is contained in the above hole transporting layer and/or hole injecting layer, whereby the organic electroluminescence device obtained by using polyarylamine is provided. In particular, materialized is the organic electroluminescence device in which a production process is simplified and which is increased in a size of a screen and a improved in device performance.
